Booming Games is quietly moving up the ladder in the slot industry, and that’s all thanks to slots such as Crystal Classics.

A game that uses the Cluster Pays engine has 7 reels populated by vintage slot symbols. The gameplay might sound complex at first, but the slot is very user-friendly once you get to know it.

Crystal Classics Slot Setup and Paytable

As most cluster pays online slots, the Crystal Classics slot uses a 7x7 setup. Instead of spinning, symbols fall into positions on the reels, which also leads to cascading wins. You score wins with 5 matching symbols in a cluster that can be positioned horizontally or vertically.

In visual terms, the slot looks quite classic, but with graphics updated for the modern era. You’ll see the reels populated by vintage slot symbols, including cherries, oranges, bells, stars, and sevens. Traditionally, sevens pay the most, delivering 100x wins for clusters of 25 or more.

The game also uses a Wild that may come with Multipliers and a Scatter that triggers the Bonus Round.

Crystal Classics Slot Mobile Gameplay

Just like all Booming Games slots, Crystal Classics is fully mobile-optimized. Thanks to the fact that it’s developed on the HTML5 platform, you can play it on your phone, no additional slot apps download required.

How to Play the Crystal Classics Online Slot?

To start playing this exciting slot game, you’ll need to place your wagers. There are only a handful of options ranging between $0.20 and $10 per spin. The range should be suitable for most players, including new and seasoned spinners.

Hit the Spin button, and the symbols will start falling from the top instead of rolling on the reels. Every win will trigger the cascading wins, giving you further chances to keep scoring wins. The more symbols you have in a winning cluster, the higher the payout. The Cascades can go on forever if you’re lucky, but considering the high variance, you’re likely to expect a few instead of dozens.

For each cluster win, between 1 and 3 Wilds may be randomly placed on the grid. These Wilds may come with x2, x3, and x5 Multipliers in the base game. Those numbers are much higher in the Bonus Round, where you can score Wild Multipliers up to 100 times your bet.

Crystal Classics Slot Free Spins Round

Getting to the Free Spins Round is possible by landing Scatters in a cluster. Four of these will get you 10 free spins, while 5, 6, or 7 deliver 15, 20, and 25 free spins in total. Three or more Scatters in the Free Spins Round add 5 more to your tally.

The gameplay in the Free Spins Round is mostly the same as in the base game, with the exception of the Wild Multipliers. They’re now much higher, so you can land wins with x100 Multipliers attached.

If you don’t want to wait for the Free Spins Round, you can buy it for prices starting from 82x your stake (on a wager level of $1).
